COMBINATION ILLUMINATING AND HEATING BURNER.

SPECIFICATION forming part of Letters Patent N o. 690,700, dated January7, 1902.

Application led July 20, 190.1.

To all whom, it may concern.q

Be it known that I, VoLNnY KING COFFILL, a citizen of Canada, residingat 'Brooklymin the county of Kings and State of New York, have inventedcertainnewand useful Improvements in a Combination Illuminating andHeating Burner, of which the followingA is a full and completespecication, such as will enable those skilled in the art to which itappertains to make and use the same.

The object of my invention is to provide a combination illuminating andheating gasburner of an extremely simple and cheap form of constructionwhich'may beinstantaneously adapted for heating or illuminating purposesand in which the amount of airmingled with the gas when the same is usedas a Bunsen or heating burner may be varied within wide limits. l

'Io such ends myinvention consists, in substance, of a burner-tube, anilluminatingburner tip mounted in theA burner-tube, a Bunsen oroutertube provided with a longitudinal air-slot having side lock-slotsincornmunication therewith adjacent to the lower end reciprocating u pand down on the burnertube, a pin or stud passing through the slot ofthe Bunsen or outer tube secured to the burner-tube adjacent to the top,an actuating-lever pivoted to the outer or Bfunsen tube adjacent to thebottom of the slot, and a support for the article to be Vheated carriedby the outer or Bunsen tube.

Int-he accompanying drawngs,formingpart of this specification, in whichlike characters of reference designate corresponding parts in theseveral views, Figure 1 is a side View of my improved form of burner inthe position assumed by the parts when the same is used as anilluminating-burner. Fig. 2 is alike view thereof, showing the same inuse as a Bunsen or heating burner. Fig. 3 is a side view, and Fig. 4 isafront view, of the illumihating-burner tip in central vertical sectionthereof, showing the form of such burner which I prefer to use. f

To form my invention, I provide a burnertube A, provided with acylindrical upper portion 10 and the lower enlarged base portion 11,which latter is provided in the wellknown way common with burner-tubeswith a female screw-thread, by which the same may Serial No. 69,058. (Nomodel.)

be afixed'in the ordinary manner to the gaspipe B of a chandelier.Fitting into the top of this burner-tube 10 is an illuminatingburner tipC, which may be of any desired form of construction, but which I preferto make of that shown, consisting of a thimble of sheet metal, the topof which is provided on opposite sides with the convex repouss cavities12, so as to leave an upwardly-extending thin central portion 13, in thecenter of which is formed the gas-outlet slot 14.V While I prefer to usean illuminating-burner tip of this particular form, I do not intend tolimit myself thereto, and any other suitable form may be used in placethereof, if desired.

Sliding easily up and down upon the burnertube 10 is the Bunsenburner-tube 15, which is provided upon one side with a longitudinal slot16, which is provided upon one side with one or more side slots 17, allof which slots are usually of the comparative length, size, and shapeshown. Secured in the burnertube 10 a short dist-ance below the topthereof and extending outward through the slot 16 of the Bunsenburner-tube 15 is a securingpn 18 of slightly smaller size than theairslot 16 and the side slot 17. The comparative lengths are such thatwhen the Bunsen burner-tube 15 is in its eXtreme lower position, so thatVthe pin 18 rests in the extreme top ofthe slot 16, theilluminating-burner C will extend slightly above 'the top of such Bunsenburner-tube, as shown in Fig. 1, in which case the device may be used asan illuminating-burner, and that when the Bunsen tube 16 is liftedupward, so that the pin 18 rests .inv the top side slot 17, the top thetip C, (shown in dotted lines in Fig. 2,)

whereby a larger flame of great heating quality may be provided, whichiame may be further increased by further lifting the Bunsen IOOburner-tube 15 up into such position that the pin 18 will rest in thelower side slot 17.

Pivoted to the lower end ot' the Bunsen burner 15 upon the side of theair-slot upon which is located the side slot 17 is an actuating-lever19, provided at the lower end with a handle 20 and at the upper end witha fulcrum-point, which extends upward a short distance beyond theupperside slot 17, and it will be seen that by throwing suchactuating-lever 20 over into the position shown in dotted lines in Fig.2 the pressure of the upper fulcrum-point 21 thereof upon the pin 18when such pin is located in either of said slots will force the Bunsenburner-tube 10 into such position that the pin 18 Will be forced out ofthe side slot and into the airslot 16, when the same will, upon therelease of the hand-lever from the pressure of the hand, drop by gravityinto the position shown in Fig. 1.

Secured upon the top of the Bunsen burnertube 15 is a suitable frame orsupport 22, usually of Wire, upon which may be supported a Vessel ofliquid or any other device which it is desired to heat.

It will be seen that by this device I have provided an extremely sim pleand cheap combined illuminating and Bumsen or heating burner in whichthe quantity of the air mixed and mingled with the gas before ignitionwhen the same is used as a Bunsen or heating burner may be quickly andeasily regulated.

Having fully described myinvention, what I claim as new, and desire tosecure by Letters Patent, is,-

In a Bunsen burner, the combination with a tube provided with aburner-tip, of a slidable and turnable tube mounted on the firstnamedtube and provided with a longitudinal slot and a plurality of lateralslots communicating therewith, said first-named tube being also providedwith a lug or pin adapted to move in said slots and said last-named tubebeing also provided with a lever pivotally connected With the lower endthereof and one end of which is adapted to bear on said lug or pin whensaid lug or pin is in one of the lateral slots or in the longitudinalslot opposite said lateral slot, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing Witnesses, this 18th day of July,1901.

VOLNEY KING COFFILL.
